The Rev. Meredith Kefauver Olsen, 38, of the All Hallows Episcopal Church in Edgewater, was confused by the initial explosion, not far behind her at the finish line she had just crossed. "I live in Federal Hill and I hear the cannons at Fort McHenry go off, and so I thought, 'Oh, this is nice, maybe it's for Patriots' Day," she said. "But right after there were lots of emergency vehicles, the police, ambulances, fire, and it wasn't just one or two. There were tons of them and they were going really, really fast."
